“…This work was successfully exploited to mass production. In 2004, Liu et al [9] utilized DEFORM-3D to combine forging with the establishment of nuts specifically for tyres, and analyzed to identify the factors that affect punch destruction. Their results revealed that an unreasonable punch size affects metal flow and increases the axial tensile stress of the punch as it exits the nut hole.…”

Abstract:The malformation of sheet metal tapping screw threads in the screw threading process increases the cost of screw threading dies and their maintenance. Die factories do not reveal their screw threading die design techniques, so production and maintenance processes are established by trial-and-error or worker experience and passing down such techniques and documenting quality control is difficult. In this study, screw thread forming design and process analysis were carried out by combining computer-aided design software with computer-aided metal forming analysis software. Simulation results were verified in an actual forming process. The sheet metal tapping screw forging size error was less than 0.90%, except at a sharp angle, which was associated with an error of 3.075%, thereby demonstrating the accuracy of the simulated forming process. The numerical analysis process can be utilized to shorten forming development time; to reduce the number of die tests, and to improve product quality and die service life, reducing the cost of development and promoting the overall competitiveness of the company.

“…Other defects such as die filling and barrel formation during the lateral extrusion process have been discussed by Tahir [8]. Similarly, Liu et al [9] studied the underfilling problem in the rotary rolling of a flange. On the other hand, Narayanasamy et al [10] studied the reaction of various metals to barreling during the cold upsetting process.…”

Geometrical defect is one of the main problems that will affect performance and perfect mating of produced parts. Coordinate measurement machine (CMM) is commonly used for the measurement, but the use of this machine is limited because of the small size and complexity of the component or features. This study aims to evaluate the defect that occurs on an AA6061 cold forging blade produced using cold forging process based on profile measurement technique. A systematic approach based on focus variation was proposed to evaluate two features, that is, roundness error and twist deviation. The profile was obtained with the use of InfiniteFocus Alicona 3D surface measurement system. Specific algorithms were developed for different cases as the evaluation of the features is discrete and the results were validated.

“…Fu et al (2008) proposed a set of criteria to evaluate metal-formed product design solutions with the aid of CAE simulation. Liu et al (2004) employed this technology to study the root-causes of tooling fracture in rotary forging process. Kim et al (2003) studied the forming process of impeller hub in order to reduce the volume of billet material via simulation.…”
